Question

If a pendulum makes exactly 60 oscillations in 15 seconds, then
its period is

Answer 1

=60÷15

=4 oscillations

Answer 2

`\Huge \boxed{\mathrm{0.25 \ s}}`

Step-by-step explanation:

`\sf \displaystyle time \ period = (time \ taken)/(number \ of \ oscillations )`

`\displaystyle (15)/(60 )=(1)/(4) =0.25`
